Input Level box
The Input Level box displays the value of Shadow Threshold, Midtone and Highlight Threshold respectively. You can also input each value here directly.
Output Level box
This box is used to expand the output level of the image color. You can either drag the triangles below the bar or enter the value directly to adjust.
If the Input Level is set as 20 to 230, then you may represent a total of 210 (230 minus 20) color levels in the image. If you set the Output Level as 10 to 250, you can “expand” the original 210 levels of color to 240 levels (250 minus 10). You can then enrich the color and add more detail in the image.
You can also click the Auto button in the dialog box to let MiraPhoto adjust the histogram properties automatically. When you have finished with adjustments, you can click OK to apply, or click Reset to restore the default settings. To abort and exit the dialog box, click Cancel.
